Description

Technical Field

[0001] This utility model relates to the field of automotive glass technology, and in particular to a double-sided symmetrical automotive low flash point glass. Background Technology

[0002] Automotive glass is a special type of glass installed on various parts of a car body to provide functions such as visibility, protection, lighting, and sound insulation. It is an important safety and functional component of a car. Traditional automotive glass often has the problems of requiring strict differentiation between the inside and outside during installation, being cumbersome to operate, and being easy to install backwards. At the same time, ordinary automotive glass is prone to producing high flash point under strong light, causing glare and interfering with the driver's vision. Therefore, there is a special need for a double-sided symmetrical automotive low flash point glass.

[0003] Chinese patent CN219792834U, published on October 3, 2023, discloses an automotive glass. By setting a hydrogen-containing DLC ​​layer and a transition layer, the adhesion of the film layers is greatly enhanced. At the same time, the addition of the transition layer greatly improves the radiation resistance of the glass, which has scratch resistance, high heat insulation and radiation resistance. However, this automotive glass has a specific direction for setting the film layers, making the installation operation complicated. If it is installed in reverse, it will seriously affect the scratch resistance, heat insulation and radiation resistance of the glass. In addition, it lacks a low flash point design, which may interfere with the driver's vision under strong light and affect driving safety. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a double-sided symmetrical low flash point automotive glass, including automotive glass 1, an installation frame 2 connected to the outer side of automotive glass 1, positioning holes 3 opened on the surface of the installation frame 2, a silicone pad 4 provided between automotive glass 1 and installation frame 2, and holes 5 opened inside the silicone pad 4.

[0024] An anti-reflective film 6 is applied to the surface of the vehicle glass 1, and a thin layer of flame-retardant silicone 7 is applied to the surface of the anti-reflective film 6. The anti-reflective film 6 and the thin layer of flame-retardant silicone 7 are used to pre-treat both sides of the vehicle glass 1. Oil, dust, and other impurities are removed by ultrasonic cleaning, followed by hot air drying to ensure the surface is dry and clean. The appropriate anti-reflective film 6 is cut to a shape that perfectly matches the surface size of the vehicle glass 1. A special optical adhesive is evenly coated on the back of the film, with the adhesive thickness controlled between 0.01 and 0.02 mm. Simultaneously, a dual-station bonding machine is activated to fix the vehicle glass 1 onto a symmetrical clamping frame, ensuring that both sides are horizontal and parallel. A robotic arm synchronously and precisely covers both sides of the vehicle glass 1 with the anti-reflective film 6, applying a pressure of 0.5 MPa to 1 MPa for roller bonding to remove air bubbles. The mixture is left to stand for 24 hours to allow the adhesive to fully cure, ensuring a tight bond between the film and the glass surface. The bonding strength on both sides is consistent, achieving a symmetrical anti-reflective effect. After the anti-reflective film 6 is installed and cured, its surface is subjected to plasma treatment to enhance surface activity and strengthen the bonding force with silicone. Flame-retardant silicone raw material with moderate fluidity is selected and thoroughly mixed in proportion using a two-component mixing device. Then, a symmetrical spraying device is used to spray the anti-reflective film 6 on both sides of the vehicle glass 1 simultaneously. During the spraying process, the distance between the spray gun and the surface is kept consistent, and the moving speed is the same to ensure that the thickness of the silicone coating on both sides is controlled at ~0.1mm-0.2mm. After spraying, the vehicle glass 1 is placed in a constant temperature curing oven at 60-80℃ and baked for 2-3 hours to allow the silicone to fully cross-link and cure. During the curing process, the glass is kept horizontal to avoid thickness deviation of the silicone due to gravity. Finally, a thin layer of flame-retardant silicone with consistent thickness, complete coverage, and symmetrical distribution is formed, ensuring that the flame-retardant performance and physical properties on both sides are completely consistent.

[0025] Furthermore, the inner wall of the mounting frame 2 fits tightly against the edge of the vehicle glass 1. The thickness of the mounting frame 2 is greater than the thickness of the vehicle glass 1. By setting the mounting frame 2, a stable wrapping can be formed around the edge of the vehicle glass 1, enhancing the overall structural strength of the glass. At the same time, its thickness, which is greater than that of the glass, can act as a buffer when the glass is subjected to external impact, preventing the glass from being damaged by direct collision with external hard objects. It also provides a stable load-bearing foundation for the installation of the vehicle glass 1. In addition, the mounting frame 2 adopts a non-directional frame. The non-directional design eliminates the need to distinguish between the front and back of the mounting frame 2, greatly simplifying the installation process, reducing the probability of installation errors, improving installation efficiency, and adapting to the usage requirements of double-sided symmetrical vehicle glass 1.

[0026] Furthermore, four identical sets of positioning holes 3 are provided on the surface of the mounting frame 2, and are symmetrically distributed at the four corners of the mounting frame 2 with respect to the central axis of the mounting frame 2. Through the setting of positioning holes 3, bolts and other connecting parts can be used to achieve precise fixing of the mounting frame 2 to the car body. The symmetrical distribution design ensures uniform force during installation, avoids stress concentration of the glass due to installation offset, and improves the stability and accuracy of installation.

[0027] Furthermore, multiple sets of silicone pads 4 are provided between the vehicle glass 1 and the mounting frame 2, and the number and position on both sides of the vehicle glass 1 correspond completely. By setting the silicone pads 4, the elastic properties of silicone can be used to fill the gap between the glass and the frame, reducing the hard friction between the two. At the same time, it plays a buffering role when the vehicle vibrates during driving, preventing the glass from loosening or breaking due to vibration. The corresponding distribution on both sides ensures the symmetry of the buffering effect.

[0028] Furthermore, multiple sets of holes 5 are arranged inside the silicone pad 4, and the holes 5 are hexagonal. The multiple sets of holes 5 are arranged in a honeycomb structure inside the silicone pad 4. Through the arrangement of holes 5, the honeycomb structure can reduce the weight of the silicone pad 4 itself, enhance its elastic deformation ability, and improve the cushioning and shock absorption effect. The uniform distribution of hexagonal holes 5 can make stress distribution more uniform, further optimizing the protective effect of the silicone pad 4 on the vehicle glass 1 and the mounting frame 2.

[0029] Furthermore, the anti-reflective film 6 has a thickness of ~0.05mm-0.1mm, and the anti-reflective film 6 completely covers both sides of the vehicle glass 1. The anti-reflective film 6 is tightly bonded to the surface of the vehicle glass 1 with an adhesive. By setting the anti-reflective film 6, the reflectivity of the surface of the vehicle glass 1 can be effectively reduced, the glare generated when strong light shines can be reduced, and the light transmission clarity of the vehicle glass 1 can be improved. The full coverage design on both sides ensures a symmetrical anti-reflective effect on both sides, so that it can play a role no matter which side the light enters from.

[0030] Furthermore, the thickness of the thin flame-retardant silicone 7 is ~0.1mm-0.2mm. The thin flame-retardant silicone 7 completely covers the surface of the anti-reflective film 6, and the thickness of the thin flame-retardant silicone 7 is completely consistent on both sides of the vehicle glass 1. By setting the thin flame-retardant silicone 7, its flame-retardant properties can be used to improve the fire resistance of the vehicle glass 1, and it can also protect the anti-reflective film 6 to prevent the film from being scratched and damaged. The consistent thickness on both sides ensures the symmetrical physical properties and flame-retardant effect of the vehicle glass 1.

[0031] Working Principle: During installation, the mounting frame 2, with its non-directional design, can tightly fit the edge of the vehicle glass 1 without distinguishing between the front and back. Its thickness, greater than the glass, provides a stable enclosure for the glass. Silicone pads 4 are filled between the two, utilizing the elastic properties of silicone to reduce hard friction. The honeycomb structure 5 inside further enhances the elastic deformation capability. When the vehicle vibrates, the symmetrical distribution of multiple sets of silicone pads 4 achieves uniform buffering, preventing the glass from loosening or breaking due to vibration. Subsequently, using the four sets of positioning holes 3 symmetrically distributed at the four corners of the mounting frame 2, along with bolts and other connectors, the entire device is precisely fixed to the car body. The symmetrical positioning design ensures uniform force during installation, preventing stress concentration due to glass misalignment and ensuring installation stability. During use, the anti-reflective film 6 on both sides of the vehicle glass 1 plays a crucial role. The pre-treated glass surface is symmetrically covered by the film through a dual-station bonding process. The thickness of ~0.05mm-0.1mm and the tightly bonded adhesive layer ensure that it effectively reduces light reflectivity, regardless of strong light from outside the vehicle. Still using in-car light sources, the films on both sides simultaneously reduce glare and improve the clarity of the glass, providing the driver with a clear view. At the same time, the thin layer of flame-retardant silicone 7 covering the surface of the anti-reflective film 6 forms double protection. The symmetrical thickness design of ~0.1mm-0.2mm not only utilizes flame-retardant properties to improve the fire resistance of the glass, delaying the spread of fire in the event of a fire, but also physically isolates the anti-reflective film 6 from external friction and collision, preventing it from being scratched and damaged. Meanwhile, the mounting frame 2 continuously plays a structural support role in daily use. Its thickness advantage forms a buffer barrier when the glass is impacted by external forces, preventing the glass from directly colliding with hard objects. Combined with the shock absorption effect of the silicone pad 4, it further enhances the glass's resistance to damage. The entire device, through the symmetrical design and coordinated operation of each component, achieves a balance between ease of installation and structural stability. By symmetrically utilizing both anti-reflective and flame-retardant functions, it comprehensively improves the safety and comfort of using automotive glass, perfectly adapting to the diverse needs during car driving. This completes the process of using a double-sided symmetrical automotive low-flash-point glass.
